A guiding mechanism for the horizontal movement of the printing carriage

Abstract

The invention discloses a guide mechanism of horizontal moving of a carriage unit of a printer. The guide mechanism comprises a carriage unit frame, wherein a guide shaft is installed on the lower portion of the carriage unit frame in a movable and penetrating mode, a guide rail which is parallel with the guide shaft is arranged above the guide shaft, a locking clip and a guide wheel which are respectively located on the front side and the rear side of the guide rail are arranged on the upper portion of the carriage unit frame, the middle of the locking clip is hinged with the carriage unit frame, and a spring which is used for enabling the locking clip to rotate around the hinged position and be pressed towards the guide wheel. The locking clip exerts force which enables the lower portion of the locking clip to be far from the carriage unit frame on the lower portion of the spring, wherein the spring is located between the carriage unit frame and the lower portion of the locking clip, and the middle of the locking clip is hinged on the carriage unit frame. According to a lever principle, the upper portion of the locking clip rotates around the hinged position and is pressed towards the guide wheel, and accordingly the guide wheel and the locking clip are enabled to tightly clamp the guide rail between the guide wheel and the locking clip, the situation that the carriage unit is closely attached to the guide rail is ensured in the horizontal moving process of the carriage unit, and the mechanism is conductive to improvement of printing quality of the printer.

Description

technical field [0001] The invention relates to a printer carriage, in particular to a guide mechanism for the horizontal movement of the printer carriage. Background technique [0002] At present, most of the domestic printers use the carriage to reciprocate horizontally along the guide rail under the drive of the drive device, so as to drive the print head to continuously reciprocate horizontally on the printing paper and print. When the carriage moves along the guide rail When moving horizontally from side to side, it is easy to be affected by vibration or external force and cannot move close to the guide rail, causing the character carriage to jump and deviate from the guide rail, resulting in unsatisfactory printing effect of the printer. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a horizontal movement guide mechanism for the character carriage which has a simple structure and prevents the...
